Too Virtual**

The cultivation methods mentioned in this book are very special. I feel that the author's writing style is concise and clear, and the writing style is easy to understand and easy to understand. The book also talks about the cultivation methods of heavenly immortals, earthly immortals and narcissus, as well as how to control the temperature of fire, etc., Which gave me a new understanding of cultivation. However, these contents require in-depth study and cannot be followed blindly. Overall, this book is quite interesting and inspired me a lot.
